# Startup Launch Checklist: Idea to First Customer

## Purpose

This recipe produces a fully operational startup — legal entity formed, MVP deployed, payment processing active, and first paying customer acquired through a repeatable channel — within 16-24 weeks. It outputs a validated sales playbook with documented CAC, conversion rates, and acquisition channel data that can be handed to hire #1 for scaling. [src1]

## Prerequisites
<!-- Agents: verify ALL prerequisites before executing. Missing prerequisites = failed execution. -->

- [ ] **Problem hypothesis** — "I believe [audience] struggles with [problem]" (can be rough)
- [ ] **Founding team** identified (solo or co-founders with complementary skills)
- [ ] **Personal financial runway** of 6-12 months or committed funding
- [ ] **Availability** to commit 40+ hours/week to the venture
- [ ] **Domain/industry knowledge** or access to target customers for interviews — if not, spend 2-4 weeks in customer discovery first

## Constraints
<!-- Hard rules. Agents: enforce throughout execution. Violating these = broken output or legal risk. -->

- Phase 1 validation requires minimum 15 problem interviews — fewer produces unreliable signal. [src7]
- Legal entity must be formed before accepting any payment, signing contracts, or opening business bank accounts. [src3]
- MVP should solve exactly one core problem well — if scope exceeds 8-12 weeks of development, it is too large. [src2]
- Pre-revenue monthly burn should stay below $15K bootstrapped or $50K funded — exceeding this compresses runway dangerously. [src5]
- First customer must be acquired through a repeatable channel, not personal favors — otherwise it does not validate the business model.

## Tool Selection Decision

```
Which path?
├── Founder is non-technical AND budget = free/$0
│   └── PATH A: No-Code Free — Carrd + Stripe + Google Sheets + manual
├── Founder is non-technical AND budget > $0
│   └── PATH B: No-Code Paid — Webflow/Framer + Stripe + Zapier + HubSpot Free
├── Founder is semi-technical or developer AND budget = free
│   └── PATH C: Code + Free APIs — Next.js/Remix + Vercel + Stripe + PostHog Free
└── Founder is developer AND budget > $0
    └── PATH D: Code + Paid APIs — Full stack + Vercel/AWS + Stripe + PostHog/Mixpanel
```

| Path | Tools | Cost (total to first customer) | Speed | Output Quality |
|------|-------|------|-------|---------------|
| A: No-Code Free | Carrd, Stripe, Sheets | $500-$2K | 12-16 weeks | Basic — functional but limited |
| B: No-Code Paid | Webflow, Stripe, Zapier, HubSpot | $2K-$10K | 10-14 weeks | Good — professional landing + CRM |
| C: Code + Free | Next.js, Vercel, Stripe, PostHog | $500-$3K | 14-20 weeks | High — custom product, full analytics |
| D: Code + Paid | Full stack, AWS/Vercel, full suite | $5K-$50K | 16-24 weeks | Excellent — production-grade from day 1 |

## Execution Flow

### Step 1: Validate the Problem (15-25 Interviews)

**Duration**: 2-4 weeks
**Tool**: Calendly (scheduling), Google Meet/Zoom (calls), Google Sheets (tracking)

Identify 30-50 potential interviewees from LinkedIn, relevant communities, or personal network. Send short outreach: "I'm researching [topic] and would love 20 minutes of your time." Conduct 15-25 problem interviews (30 min each) using open-ended questions. Ask: "What's the hardest part about [domain]?" and "What have you tried?" — never pitch your solution. Document pain intensity (1-10), frequency, current solutions, and willingness to pay. [src7]

After problem interviews, run 10-15 solution interviews. Present a rough solution concept and ask: "Would this solve your problem?" and "What would you pay?" Push for concrete commitments: beta signups, deposits, introductions to decision-makers. [src1]

Calculate TAM/SAM/SOM using bottom-up methodology. Map 5-10 competitors and identify positioning gaps. [src5]

**Verify**: 10+ interviewees confirm same pain point; 3+ express willingness to pay; SAM exceeds $10M
**If failed**: If <30% recognize the problem after 20+ interviews, pivot the problem hypothesis or stop

### Step 2: Form Legal Entity

**Duration**: 1-3 weeks
**Tool**: Stripe Atlas ($500) or DIY state filing ($89-$200)

Choose entity type based on funding path:
- **VC-track**: Delaware C-Corp — no exceptions. VCs require preferred stock. [src3]
- **Bootstrapped**: LLC (pass-through tax) or S-Corp (salary + distribution tax optimization)

```bash
# Option A: Stripe Atlas (recommended for speed)
# 1. Go to stripe.com/atlas
# 2. Complete application (15 minutes)
# 3. Entity active in 1-2 business days
# Includes: Certificate of Incorporation, EIN, bylaws, restricted stock purchase agreements

# Option B: DIY Delaware Filing
# 1. Check name availability at corp.delaware.gov
# 2. File Certificate of Incorporation ($89 state fee)
# 3. Appoint registered agent ($50-$300/year)
# 4. Apply for EIN at irs.gov (free, immediate)
# 5. Draft bylaws and restricted stock agreements
```

After formation: open business bank account (Mercury recommended for startups), set up founder vesting (4-year with 1-year cliff), execute IP assignment agreements, and file 83(b) elections within 30 days of stock grant. [src3]

**Verify**: Entity registered with state; EIN obtained; bank account open; founder agreements signed; 83(b) filed
**If failed**: If filing rejected, correct name conflicts or document errors and refile. If bank application pending, use personal account temporarily (track separately)

### Step 3: Build MVP (One Core Feature)

**Duration**: 4-8 weeks
**Tool**: Per path — see Tool Selection Decision above

Define MVP scope: one core feature that solves the #1 validated pain point. Use MoSCoW prioritization — only "Must-have" features in V1. Reference [MVP Scoping Framework](/business/startup/mvp-scoping-framework/2026) for detailed feature selection. [src2]

```
MVP Scope Checklist:
[ ] One-sentence value prop: "We help [audience] achieve [outcome] by [approach]"
[ ] Core user journey: 5-8 steps from signup to value delivery
[ ] Must-have features: 3-7 (use deletion test — if removed, can user still get value?)
[ ] Non-functional requirements: auth, data persistence, basic security
[ ] Cut list: everything else goes to V1.1 backlog
```

Build in 1-week sprints with user feedback loops. Deploy to production environment. Set up basic analytics (PostHog free tier: 1M events/month). [src6]

**Verify**: Beta users can complete the core workflow end-to-end; no critical bugs blocking usage
**If failed**: If MVP scope exceeds 8 weeks, cut features. If critical bugs found, fix before proceeding. [src2]

### Step 4: Launch to Beta Users (5-15 Users)

**Duration**: 2-4 weeks
**Tool**: Email (personal onboarding), PostHog/Mixpanel (analytics), Stripe (payments)

Personally onboard 5-15 beta users from Step 1 interview list. Provide white-glove support — observe how they use the product. Collect feedback daily: what works, what is confusing, what is missing. Track activation metrics: signup-to-value time, feature usage, return rate. [src1]

Test 2-3 pricing tiers with different segments. Use Van Westendorp methodology for price sensitivity. Set launch pricing — anchor on value delivered, not cost to serve. [src6]

Update landing page with pricing, features, and social proof from beta users. Set up payment processing (Stripe). Create self-serve onboarding flow.

**Verify**: 5+ beta users actively using product weekly; pricing tested without rejection; payment processing works
**If failed**: If engagement below 30% weekly active, revisit core value prop and onboarding flow

### Step 5: Acquire First Paying Customer

**Duration**: 4-8 weeks
**Tool**: Cold email tool ($50-$200/mo), LinkedIn, CRM (HubSpot free)

Test 2-3 acquisition channels simultaneously:
- **B2B**: Founder-led outbound — 50-100 personalized emails/week + LinkedIn outreach
- **B2C**: Community-driven launch (Product Hunt, Reddit, Twitter/X)
- Track cost per lead, lead-to-trial conversion, trial-to-paid conversion [src6]

```
Channel Testing Framework:
Week 1-2: Launch on primary channel (B2B: cold email; B2C: community)
Week 3-4: Add secondary channel if primary shows signal
Week 5-8: Double down on best-performing channel

Minimum viable metrics per channel:
- 2 weeks of consistent effort before evaluating
- 100+ outreach attempts (B2B) or 200+ visitors (B2C)
- Track: impressions → leads → trials → paid conversions
```

Founders must close the first 10 customers personally. Document every objection and reason for loss. Offer early-adopter incentives (discounts, extended trials) but not free forever. [src4]

**Verify**: First customer paying; acquisition channel identified with estimated CAC; customer actively using product
**If failed**: If 200+ outreach attempts with zero conversions across multiple channels — fundamental market-demand issue; return to Step 1

### Step 6: Post-Sale Validation and Playbook

**Duration**: 2-4 weeks after first sale
**Tool**: CRM (HubSpot), analytics, direct customer check-ins

Monitor first customer usage closely — weekly check-ins. Measure time-to-value: how quickly do they get the promised outcome? Ask for referrals and testimonials. Document the end-to-end sales process for future replication. [src1]

**Output files**:
- `sales-playbook.md` — Documented sales process: channel, messaging, objection handling, close rate
- `customer-profile.md` — First customer profile, use case, time-to-value metrics
- `channel-performance.csv` — CAC, conversion rates, cost per channel tested

**Verify**: First customer still active after 30 days; sales process documented; at least one referral or testimonial obtained
**If failed**: If first customer churns within 30 days, treat as product-market fit failure and return to Step 1 validation

## Quality Benchmarks

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Problem interviews completed | 15 | 20 | 25+ |
| Beta user weekly active rate | >30% | >50% | >70% |
| Time to first paying customer | <24 weeks | <16 weeks | <12 weeks |
| Customer acquisition cost (B2B SaaS) | <$500 | <$200 | <$100 |
| First-month retention | >50% | >70% | >85% |

**If below minimum**: Re-run Step 1 with broader customer segment, or pivot solution approach based on feedback data.

## Error Handling

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| Cannot recruit 15 interviewees in 2 weeks | Target audience too narrow or hard to reach | Broaden customer profile; try different sourcing channels (Reddit, paid user research platforms) |
| Entity formation rejected | Name conflict or document errors | Check name availability at corp.delaware.gov; correct and refile |
| MVP development exceeds 8 weeks | Scope too large; feature creep | Return to MVP scoping; cut to 3-5 must-have features only [src2] |
| Zero beta user engagement after onboarding | Product does not deliver promised value | Conduct 5 user observation sessions; identify where users drop off; fix core workflow |
| 200+ outreach attempts, zero conversions | Product-market fit issue or wrong channel | Test different messaging; try alternative channels; if persistent, return to Step 1 [src1] |
| 83(b) election deadline approaching | Filed restricted stock but forgot 83(b) | File immediately via certified mail to IRS — hard 30-day deadline, no extensions [src3] |

## Cost Breakdown

| Component | Bootstrapped (<$10K) | Friends & Family ($10K-$50K) | Pre-Seed Funded ($50K+) |
|-----------|---------------------|------------------------------|------------------------|
| Legal formation | $500-$1,500 | $1,000-$3,000 | $2,000-$5,000 |
| MVP development | $0-$5,000 | $5,000-$25,000 | $15,000-$50,000 |
| Brand & domain | $100-$300 | $300-$1,000 | $1,000-$3,000 |
| Tools & subscriptions | $50-$200/mo | $200-$500/mo | $500-$1,500/mo |
| Marketing & launch | $0-$500 | $500-$2,000 | $2,000-$10,000 |
| Contingency (20%) | $200-$1,500 | $1,500-$6,000 | $4,000-$14,000 |
| **Total to first customer** | **$1,000-$10,000** | **$10,000-$40,000** | **$25,000-$85,000** |

[src8]

## Anti-Patterns

### Wrong: Building for 6 months before talking to customers
Founders spend months perfecting features no one asked for, then launch to silence. 42% of failed startups cite "no market need" as the #1 cause of failure. [src7]

### Correct: Talk to 15+ customers before writing a single line of code
Spend 2-4 weeks validating that the problem is real and someone will pay for a solution. This is the cheapest insurance against building the wrong thing. [src1]

### Wrong: Hiring a sales team before founders close the first 10 deals
Founders hire experienced salespeople expecting them to "figure out the sales process." Without a proven playbook, even talented salespeople will fail and burn cash. [src4]

### Correct: Founders personally close the first 10 customers
Only founders have enough context to handle early objections, iterate on positioning, and extract learning from every conversation. Document everything, then hand the playbook to hire #1. [src4]

### Wrong: Launching on every channel simultaneously
Spreading thin across Product Hunt, paid ads, content marketing, cold email, and partnerships — each getting 20% effort — means none get enough investment to generate signal. [src6]

### Correct: Pick 1-2 channels, invest heavily, measure for 2+ weeks
Choose channels based on where your target customers already spend time. B2B: LinkedIn + cold email. B2C: community + content. Test each for at least 2 weeks before evaluating. [src1]

## When This Matters

Use when a founder or agent needs to execute a startup launch from idea to first paying customer — not plan it, but actually build and ship. Requires a problem hypothesis as input; produces a revenue-generating entity as output.
